To @ZZ whom t may Be it known that I, Flinn A. HOLMES, a citizen of theUnited States, residing at Eastport, in the county of Washington andState of Maine, have invented a new and useful Ice-Cream Freezer, ofwhich the following is a specification.

This invention vrelates to refrigerating apparatus, and has for itsobject to improve the construction and increase. the efficiency Aandutility of devices of this character.

With these and other objects in view, which will appear as the nature ofthe'invention is better understood, the same consists in certain novelfeatures ofconstruction, as hereinafter fully described and claimed. x

In the accompanying drawings, forming a part of this specification, andin which corresponding parts are denoted by like designating characters,is 4illustrated the preferred form of embodiment of the inventioncapable of carrying the same into practical operation.

In the drawings, Figure 1 is a longitudinal sectional elevation, andFig. 2 is a transverse l section on the line 2 2 of Fig. 1 of the i-rn,

proved apparatus. The improved apparatus comprises an outer casing orshell 10, referably 1n circular shape and with the sid) ductivematerial, such as Wood lined with asbestos, the latter indicated at 11.The casing 1() is provided with a detachable cover 12, resting 'upon anannular cleat 13, and with a centralvaperture 14. Within the outercasing 10 and near its lower end is a transverse partition 15, spacedfrom the bottom and forming a dead-air chamber 16, the partition beinglikewise of non-conductive material, such as wood. Disposed within theouter casing 10 is an inner casing 17, spaced from the outer casing andsupported upon the partitions 15. The walls of the caslng 17 are ofnon-conductive material, such as Wood, and lined with sheet metal, as at18, and with a detachable cover 19, also of Wood or other non-conductivematerial, and with a sheetmetal casing-sheathing 20, the sheathing and.

cover having central apertures 21 in alinement with the aperture 14 inthe cover 12 of the outer casing. The Wood portion 19 of the cover ofthe inner casing bears inside the side Walls of the inner casing, whilethe sheath- -ing 20 is provided with a flange 22, depending over theouter face of the side Walls of the casing 17 as shown in Fig. 1. Bythis means e walls' of non-con- .i @fclose and Substantially .air-,tightjoint formed between the'"i'rinercasing an'd""its cover. a bail'23, bywhich to handle the same.

' Formed within the casing 17 is an interior chamber 24, open at thelower end and with its upper end spaced below the detachable cover 19 ofthe inner casing. Rising from the top member 25 of the chamber 24 is aPatented March 2.7,

The inner casing 17 is provided with ,i

tube 26, extending through the apertures 21 of the cover 19 and itssheathing 20. A detachable plug 27 is inserted through the aperture 14in the closure 12 and is seated in the upper end of the tube 26 toprovidea ready means of closing the tube and apertures when required.

The various casln s and chambers can be of-any required size andemployed for refrigerating any required materials or products orarticles, but is more particularly designed for preserving ice-cream andlike products for an indefinite time and in position for ready accesswhen required.

In o erating the device the inner casing 17 is fille with therefrigerating material, such as ice commingled with salt and indicatedat The tube 26 provides already means for Ventilating the chamber 24 ifarticles are placed therein which require ventilation, and the tube mayalso be employed for receiving lthe handle of an ice-cream freezer whenthe device is utilized to support. an ice-cream freezer Within thechamber 24.

It will thus be noted that when all the parts are assembled the internalstoragechamber is completelysurrounded by ice, except at the bottom, andthat both the storage-chamber and lice-chamber are completely surroundedby the deadair spaces, which forms an effectual nonconducting packingand materially increases the eiiiciency of the device. .Havingthus-described the invention, what is claimed is- In a refrigeratingapparatus, an outer casing having a detachable cover provided withvl IOOIIO

tition spaced from the bottom of the casing and forming a dead-air spacein the bottom of the same, an inner casinor spaced from the outer easingand supported upon said partition7 said inner casing having a detachablecover and with an internal chamber opening downwardly, a tube extendingfrom said chamber through the cover to said inner oasing and inalinement with the aperture in the I0 cover to the outer easing and adetachable plug extending through the aperture in said outer casing andseated in said tube.

In testimony that I claim the foregoing as my own I have hereto aHiXedmy signature in the presence of two witnesses.
